So todays progress... wifi working .. i can get 1.9Kb/s download... woooooo!

But more importantly i can get onto Aminet and I can run WookieChat.. #Amiga-IE on Freenode being my destination.

I did some measurements... I have missed 2 wires from the edge connector to my CPLD.. EXP_BR and EXP_BG.. Akiko does some DMA cycles where it asks the CPU to STFU.. and I dont handle this... So i think thats why the drive doesnt work. A rev2 will be needed.

I guess I will use my TF530 to test which cpu will run at 50 mhz.

EDIT: just plugged in a 33 mhz and it runs at 50 no issues. Yet I couldn't get a 25 to run at 33. Go figure. The luck of the draw I guess.
EDIT2: nvm, it crashed after 10 mins :)

I used a 33Mhz Plastic for my 24 hrs soak test. Perhaps more likely to work in the TF330 with its clock switching to 14Mhz.... gives the CPU a break here and there maybe?

Thanks for the great work Stephen and everyone else on the project.

I was wondering what performance we can expect from the TF330. I remember to have seen something around the lower 6000's "dhrystones" in sysinfo. While it's a considerable boost obviously, it's still a bit behind what 030 boards can do afaik (8-9000k). Is it due to "safe mode" that I think was mentioned, or perhaps the 50 - 14 cycling? Do you think the final rev can improve on this?

I'm getting one anyway, just curious. Please keep up the awesome work. :)

Currently getting 6813 Dhrystones with the ram in dumb
Safe mode. Expecting 9000 once burst mode is enabled

The 14/50 cycling makes no difference as the cpu would be in wait states either way. It just makes transitions more reliable.

I’ve not worked on performance because I had a demo with the board today. It ran for hours without a single crash.

Aww...What's happened? You was trying to add flywires from riser? Yeah, same is on A2000 CPU Slot - all voltages present, so need to be really careful...
Hopefully Your new CD32 isn't damaged...
